WebIf we don’t apply any compression algorithms such as path compression or Union by rank, the time complexity for Kruskal’s algorithm is O(E* log(E) + E ^ 2). This is because we are sorting the edges, which costs us O(E * log(E)) time, and further, we are using a disjoint set, which costs us a total of O(E ^ 2) time.
